Origin
The surname SOSIN has its origins in Poland, and can be traced back to the 16th century. It is believed to be derived from the Polish word "sosna," meaning "pine tree," suggesting that the name may have originated from someone living near a pine forest or working with pine trees.
One of the earliest recorded instances of the SOSIN name can be found in the Polish town of Krakow, where a record from 1587 mentions a person named Jan SOSIN. This document suggests that the name was already well-established in the region at that time.
Another early reference to the SOSIN surname can be found in the town of Poznan, where a record from 1612 mentions a person named Marcin SOSIN. This record provides evidence that the name had spread to other parts of Poland by the early 17th century.
During the 17th and 18th centuries, the SOSIN name became more prominent in various regions of Poland. One notable individual from this period was Jakub SOSIN (1660-1732), a Polish Catholic priest and theologian who wrote several influential works on religious philosophy.
In the 19th century, the SOSIN name continued to be well-represented in Poland. One of the most famous individuals with this surname was Władysław SOSIN (1832-1902), a Polish painter and artist who specialized in landscape and genre paintings.
As Polish immigration to other parts of the world increased in the late 19th and early 20th centuries, the SOSIN surname began to appear in other countries as well. One prominent example is Józef SOSIN (1889-1954), a Polish-American architect who designed several notable buildings in Chicago and other parts of the United States.
While the SOSIN name has its roots in Poland, it has since spread to various parts of the world, with notable individuals bearing this surname in countries such as the United States, Canada, and Australia.
Demographics
Among Census respondents with the surname Sosin, the largest self-reported group is White at 93.2%. The next largest groups are Hispanic (2.9%) and Two or More Races (2.9%).
The bar chart below shows how Sosin bearers described their own race and ethnicity on the 2020 Census form. The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Sosin surname at the time of the 2020 Census, not any inherent property of the name itself.

No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
